[calmly] Ah, well, I attended Juilliard, I am a graduate of the Harvard Business School, I travel quite extensively, I lived through the Black Plague and I had a pretty good time during that, [getting aggressively more demented] I've seen The Exorcist about 167 TIMES,AND IT KEEPS GETTING FUNNIER EVERY SINGLE TIME I SEE IT!NOT TO MENTION THE FACT THAT YOU'RE TALKING TO A DEAD GUY!NOW WHAT DO YOU THINK?![calmly] You think I'm qualified?

Beetlejuice: [refined voice] Ah, well... I attended Juilliard... I'm a graduate of the Harvard Business School. I travel quite extensively.
